Tender boneless and skinless chicken thighs stuffed with spinach and ricotta cheese, and then baked to golden perfection in a simple marinara sauce.

When it comes to chicken, I’ve always favoured dark meat over breast meat. I know the breast meat is leaner and healthier, but unless it’s grilled or smothered in sauce, I always opt for the dark.
When I decided to make this Spinach and Ricotta Stuffed Chicken, I immediately decided to use boneless and skinless thigh meat. I knew it would result in a juicier chicken dish.
I can properly cook a chicken breast without it turning into a dry choking hazard. But, to eliminate the risk of the chicken being too dry, chicken thighs were the way to go!

I’ve been cooking a lot more with the combination of spinach and ricotta. I think they are two ingredients that pair very well together. And, there seems to be an endless use for them both in terms of recipes.
It was time I started to photograph some of these dishes and get them posted to Lord Byron’s Kitchen so that you could enjoy them too, Dear Reader! Let’s talk about the chicken.
How to flatten the chicken:
If you’ve used boneless skinless chicken thighs before, you’ll know that one side is smooth and glossy, while the other side is ragged and torn. This, of course, is the result of cutting the meat away from the bone.

For this recipe, you’ll want to flatten (or pound) the thigh meat so that the entire thing is evenly smooth. If you have a meat tenderizer, you can use that. Just be sure to use the flat side, not the spiky side!
I don’t own a lot of fancy kitchen tools, so I always improvise. Here’s how I like to pound the chicken. Place a large cutting board on your countertop. Place a sheet of parchment paper or plastic wrap on top of the cutting board.
Open the chicken thigh up – it’s usually rolled up in the package. Lay it flat on the board and top the chicken with another sheet of parchment or plastic wrap. Now, go get your rolling pin!

Using your rolling pin, firmly pound the pin down flat onto the thigh. Be sure to move around, gently pounding out the meat until it’s flat. You’ll want the chicken to be about 1/4 of an inch thick.
If you have spots that are too thin, don’t worry about it. It’s not going to make any difference at all. Just don’t leave thick parts, because it might not cook all the way though.
Place the pounded chicken on a plate and move onto the next piece. You can certainly re-use the same parchment paper or plastic wrap. My parents used to always say, “Waste not; want not!”

Now what?
Now that the chicken has all been pounded and laid out flat on a plate or platter. Lightly salt and pepper the chicken. Next, evenly distribute the spinach and ricotta mixture onto the chicken.

Don’t spread the mixture out! Elongate the mixture at the widest end of the chicken. Now, roll the chicken up, sealing in the ricotta mixture. There is no need to pierce the chicken with a toothpick to hold everything in place.
Set the stuffed chicken thighs, seam side down, into the baking dish that has been prepared with the marinara sauce. Top with the parmesan and black pepper. Bake for 30 minutes. That’s it – you’re done! It was easy, right?

Now, plate it up and enjoy! I like to serve this chicken with steamed brown rice. It’s also really good with pasta. It’s like a jacked up chicken parmesan! Oh, and this dish reheats very well the next day if you want to take any leftovers for lunch!

SHUT THE FRONT DOOR. This recipe was absolutely delicious! Made it for my family and everyone loved it. Adding to my weekly menu. Also left out the chili flakes because I didn’t have any and it was still awesome. Can’t wait to try more recipes.

I was a little confused about the wrapping of the flattened thighs, but made it work even if it was sloppy. Tasty dish, boyfriend enjoyed it. Probably add it to the cheap/easy weekday meal list. I did have to change the cooking time and temp – 350 for 30 minutes didn’t bring up the temp correctly for 4-thighs. I did an additional 20-minutes at 400 and that worked just fine. Next time I’ll probably do 400 for 45-min.

Since there are only 2 of us, could I prepare the dish, freeze half of it for later? If so, would I thaw it completely then follow the above baking instructions.
Thanks, Janet

Excellent. Hubby said it was my best dish to date – 21 years together?! I added chopped basil and an egg to the mixture. I also used fresh spinach. And, like someone said above, I had to cook it much longer. I used some pasta sauce and a small can of cut up tomatoes with Italian seasoning as well as chicken breast to cut the calories. Thanks!
